Disable sealed mode on a SOBR extent.
AI agents use DisableScaleOutExtentSealedMode to create or update resources in Veeam VBR v13 MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Veeam VBR v13 MCP Server environment.
This tool modifies backup repository configuration (disabling sealed mode) rather than reading, executing arbitrary operations, or destructively deleting data. Sealed mode typically prevents writes to ensure immutability; disabling it could allow subsequent writes or modifications to backup data, making this a Write-class operation.
From the tool's definition Tool name 'DisableScaleOutExtentSealedMode' indicates modification of SOBR (Scale-Out Backup Repository) extent configuration by disabling a sealed mode setting.
Attacks that exploit this kind of access
Disable sealed mode on a SOBR extent. It is categorised as a Write tool in the Veeam VBR v13 MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Veeam VBR v13 MCP Server MCP server in PolicyLayer and add a rule for DisableScaleOutExtentSealedMode: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Veeam VBR v13 MCP Server. Nothing to install.
DisableScaleOutExtentSealedMode is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the DisableScaleOutExtentSealedMode rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for DisableScaleOutExtentSealedMode. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
DisableScaleOutExtentSealedMode is provided by the Veeam VBR v13 MCP Server MCP server (kid-boy/veeam-mcp-13). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
